Specification of Letters Patent.

Patented Feb. 6, 1917.

Application filed March 28, 1916. Serial No. 87,240.

To all whom it may concern Be itknown that I, I-IENRY LOUIS Korm- LER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Delivery Attachments for PrintingPresses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to printing presses, and more particularly to a delivery mechanism for a printing press.

One of the principal objects of the invention is to provide a delivery mechanism embodying improved features of simplicity of construction and operation, and to provide a delivery mechanism which is associated with the main frame of a printing press and operatively connected with the main shaft of the ress.

ith these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which characters of reference are used to indicate various parts shown in the figure, which illustrates a side elevational view of a delivery mechanism of the preferred form of my invention, showing the same as attached in operable position on a rinting press.

eferring more particularly to the drawing, the numeral 5 indicates generally the press, which may be of other forms than shown, but which is here illustrated as comprising a frame 6, an impression cylinder 7, secured on a driven shaft 8, journaled in said frame, a feeding mechanism indicated generally by the numeral 9, and an inclined delivery table 10.

The delivery mechanism comprises a pair of connected frames each formed of a horizontally disposed side arm 11, provided at its inner end with a vertical slot 12 disposed over the shank of a beaded stud 13, which stud may actually be the extended end of a rod for bracing the press frame, a vertically disposed arm 14 extending downwardly from arm 11, near the inner end thereof; a substantially arcuate brace 15, connecting arm 11, near the outer end thereof, with the lower end of arm 14:, and extended and slotted longitudinally at its lower end or at 16 for removable attachment to a stud 17 near the bottom of the press frame, and a right angular bracket comprising a vertical and a horizontal arm 18 and 19 respectively, connected to the outer end of arm 11 and to brace 15'below last said arm.

The frames thus described are removably attached as pointed out, one to each side of the press frame, and said delivery frames are connected by a truss rod 20, and by a shaft 21 journaled in the frames at the meeting points of arms 11 and 18.

On one of the frames beneath end of shaft 21 and in spaced relation thereto,-is pro- Vided a pin 22 on which is pivoted near its central portion, an angular lever 23, having its upper end on the side directed toward the adjacent frame, longitudinally slottedas at 24, and in this slot works a roller 25, journaled on a pin 26 extending at right angles fromthe outer end of a crank arm 27, which is keyed to the adjacent end of the shaft 21.

A delivery fan 28 is fixedly connected at its lower end to shaft 21, between the frames of the delivery mechanism, and rests at its upper end in a rabbet 29 formed in the lower edge of inclined delivery table 10, the upper surface of fan 28 thus being flush with the upper surface of table 10, at the meeting edges of said surfaces, so that material having passed under the impression cylinder and having been printed thereby, will slide over table 10 onto the upper end of fan 28, so that when shaft 21 is turned, in a manner to be described, and with it fan 28,

through an angle of approximately 160, the printed material will be delivered in an approximately horizontal position rearwardly of the delivery frames.

In order to actuate lever 23 for rocking shaft 21, the lower end of said lever is connected by means of a link 30, with the lower end of a long lever 31, pivoted above its central point and intermediate its ends to the press frame as at 32, and the upper end of lever 31 is provided with a pin on which a roller 33 is j ournaled, said roller engaging a grooved cam 34 secured to the adjacent end of shaft 8, whereby as the printing drum rotates during the process of printing material, the lever 31 is rocked, and consequently shaft '21 and fan 28 for intermittently delivering the printed matter, it being understood of course that the means for opto the frame of the press, I do not confine myself to this exact construction as I may construct the frame of the delivery i'nechanism as an integral part of the main frame of the press if so desired.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts as do not depart from the spirit of the invention and the scope of the appended claims.

Having thus fully described my invention what I claim as new and desire to secure by Letters-Patent is:

1. In combination with a printing press frame, a sheet delivering mechanism com- Gopies of this patent may be obtained for prising an auxiliary frame, a pivoted delivery fan carried by the auxiliary frame, studs carried by the press frame, arms having slots, forming a part of the auxiliary frame, the slots of the arms adapted to embrace the studs for removably supporting the auxiliary frame, and means for actuatingthe fan.

2. In combination with a printing press and the main frame thereof, a sheet delivering mechanism comprising an auxiliary fan frame having horizontally disposed side arms, arcuate brace arms forming a part of the frame, means carried by the main frame for cooperating with the side arms and arcuate brace arms for removably securing the auxiliary frame to the main frame, and means for actuating the sheet delivering mechanism.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
